Abstract (en)
[origin: EP0398394A2] The invention provides a reservoir assembly for removable engagement with a motor drive, comprising a reservoir; and a piston (13) having a fluid contacting head portion located within the reservoir and a drive body (12) for engagement with a motor drive and having an aperture (121) therein. There is provided a severable stem (131), removably attaching the fluid contacting head portion to the drive body (12), protruding from the fluid contacting head portion through the aperture (121) in the drive body (12) sufficiently far to prevent the drive body (12) from being engaged with the motor drive without the stem (131) first having been severed, so that when the piston (13) is placed in engagement with the motor drive the head portion is detached from the body and retraction of the head portion and refilling of the reservoir are prevented.
